Question

STATEMENT-1 : A cyclist is cycling on a rough horizontal circular track with increasing speed
Then the net frictional force on cycle is always directed towards centre of the circular track
STATEMENT-2 : For a particle moving in a circle, component of its acceleration towards centre,
that is, centripetal acceleration should exist (except when speed is zero instantaneously).
(A) Statement-1 is True, Statement-2 is True; Statement-2 is a correct explanation for Statement-
1.
(B) Statement-1 is True, Statement-2 is True, Statement-2 is NOT a correct explanation for
Statement-1
(C) Statement-1 is True, Statement-2 is False
(D) Statement-1 is False, Statement-2 is True​

Answer 1

Answer:

STATEMENT-1 : A cyclist is cycling on a rough horizontal circular track with increasing speed

Then the net frictional force on cycle is always directed towards centre of the circular track

STATEMENT-2 : For a particle moving in a circle, component of its acceleration towards centre,

that is, centripetal acceleration should exist (except when speed is zero instantaneously).
